PTMEG Polyether Polyol Safety Storage and Transportation Specification

1. Introduction

PTMEG (polytetrahydrofuran ether glycol) is an important raw material for chemical production, widely used in polyurethane, elastomer, fiber and other fields. Due to its special chemical properties, the storage and transportation of PTMEG must follow certain safety regulations to ensure personnel safety and environmental protection. This paper will detail the safe storage and transportation specification of PTMEG.

2. the physical and chemical properties of PTMEG

PTMEG is a colorless to light yellow transparent liquid with low viscosity, good hydrolytic stability, oxidation resistance and thermal stability. However, PTMEG is flammable and can cause combustion and explosion in case of open flame, high heat or contact with oxidant. Therefore, understanding and mastering the physical and chemical properties of PTMEG is essential for its safe storage and transportation.

3. the safety of PTMEG storage specification

1. Storage facilities: PTMEG should be stored in a cool, ventilated special warehouse. The warehouse shall be far away from fire and heat sources and equipped with fire fighting equipment. The ground shall be non-slip to prevent slip caused by PTMEG leakage.
2. Storage container: PTMEG should be stored in a special stainless steel or plastic container, avoiding the use of iron, copper and other metal containers to prevent chemical reactions. The container should be well sealed to prevent PTMEG volatilization and external impurities from entering.
3. Storage temperature: The storage temperature of PTMEG should be controlled below 25 ℃ to avoid direct sunlight. Excessive temperature may cause decomposition of PTMEG and cause safety accidents.
4. Storage capacity: The PTMEG storage capacity of a single storage facility should not exceed its maximum allowable storage capacity to prevent excessive losses in the event of an accident.

4. PTMEG safety transport specifications

1. Transport vehicles: PTMEG should be transported by special chemical transport vehicles, which should have good sealing and shockproof performance to prevent PTMEG leakage and damage during transportation.
2. Transport personnel: Transport personnel shall be professionally trained to understand the nature of PTMEG and safe transport specifications, and have the ability to respond to emergencies.
3. Transportation route: The transportation route should choose the route with smooth roads and good traffic conditions as far as possible, and avoid passing in prosperous urban areas or densely populated areas.
4. Transport packaging: The packaging of PTMEG should comply with relevant standards, and the packaging should be tight and firm to prevent damage or leakage during transportation. The packaging shall be clearly marked with information such as the name of the article, the danger and the countermeasures.

5. emergency treatment measures

During the storage and transportation of PTMEG, the following emergency treatment measures shall be taken in case of any accident:

1. Personnel evacuation: evacuate nearby personnel immediately to avoid casualties.
2. Cut off the fire source: If a fire occurs, cut off the fire source immediately and use corresponding fire extinguishing equipment to extinguish the fire.
3. Leakage treatment: In case of PTMEG leakage, special equipment should be used to recover the leakage to avoid environmental pollution. At the same time, the leakage area is ventilated to eliminate potential safety hazards.
4. Medical assistance: If any person is exposed to PTMEG or has symptoms of poisoning, they should be sent to the hospital immediately for treatment.

6. conclusion

PTMEG as an important raw material for chemical production, its safe storage and transportation is very important. By understanding and mastering the physical and chemical properties of PTMEG and strictly complying with its safety storage and transportation specifications, safety accidents can be effectively prevented, personnel safety and environmental protection can be guaranteed.
